the word 'topknot' is a transparent compound formed from two old english, germanic-derived elements. 'top' originally referred to the highest point or summit, and by extension, the crown of the head or a tuft of hair growing there. 'knot' descends from a common germanic root for a tied fastening. when combined, the term literally means "a knot on the top," a logic perfectly preserved in its modern meanings. it first described a decorative ribbon tied atop the head, later extending to similar hairstyles for people and natural crests on animals, maintaining a direct link between its constituent parts and its application.
